Application filed September 17, 1913. Serial No. 790.266.

T 0 all 'whomit mayl concern.' e

Be it known that I, HENRY GRUsoNG, a citizen of the United States,residing at Cresson, in the county of Cambria and State of Pennsylvania,have invented certainnew and useful Improvements in Wheel-Mounts, ofwhich the following is a specification, reference being had to theaccompanying drawings. v

This invention comprehends certain new and useful improvements introlley poles and heads and has for its primary object to provide atrolley pole and head which will be of such construction and operationas to allow the trolley wheel mounted in the head to turn to variouspositions without leavingI the trolley wire. f

Another object is to provide adevice of `this character in which theportion of the trolley pole upon which the head is mounted will be freeto rotate limited distances in opposite directions while the head ismounted` upon said portion of the trolley pole in such manner that saidhead may be free to turn as far as necessary in either direction whenthe caris turning the corner or rounding 'a curve, without danger of thewheel leaving the trolley wire, as sometimes happens inthe ordinaryconstruction.

A further object is to generally improve and simplify the constructionand operation of devices of this character and increase the efficiencyof the same.

With the above and other objects in view, my invention conslsts 1ncertain novel con structions, combinations, and arrangements of parts tobe hereinafter more fully described, claimed, and illustrated' in theaccompanying drawings, in'which,

Figure 1 is a longitudinal sectional view through the complete device;Fig. 2 is an elevational View. of the same; Flg. 3 is a detail crosssectional view on the line 33 of Fig. 1, looking in the directionindicated by the arrow: Fig. 4 is a top plan view of the device; Fig. 5is a detail cross sectional view on the line 5-5 of Fig. 1, with thecurrent conducting wire removed; and Fig. 6 is a 4detail elevationalview of the trolley head removed, said View showing the rear or innerface of the same.

Referring more specically to the drawings in which similar referencecharacters designate corresponding parts throughout the several views, 1designates the main portion of the trolley pole, upon the end of mainportion l of the trolley pole to limit.

rotation of the rotatable portion 3 of said trolley pole. A bearingblock 6 is mounted upon the upper extended end of the rotatable portion3 of the trolley pole and has the socket 7 formed therein and extendinginwardly from one face 8 thereof to receive the bearing sleeve 9projecting laterally from the corresponding fiat face 10 of the trolleyhead 11. A bearing member 12 extends longitudinally through the centerof the socket 7 and bearing and sleeve and has `one end mounted in theend wall of the socket while its opposite end extends through the face10 of the trolley head 11 and has a nut or other suitable means 13secured thereon, the first mentioned end of the bearing member havingthe head 14 formed thereon, which head is preferably countersunk in theouter-face of the bearing block 6.

, The trolley head 11 is suitably forked, as shown at 15, and has ashaft 16 mounted in its forked portion with a trolley wheel 17 looselymounted thereon.

It will be understood that the conducting wire 18 maybe connected withthe stationary sleeve 2, as shown at 20, or in any other suitablemanner,` and secured to the main portion 1 of the trolley pole, as shownat 21. It will also be understood that the sleeve 2 is suitablyinsulated from the main portion of the trolley pole. i

From the foregoing, it will be clearly apparent that I have constructedand connected the trolley pole and head in such manner that the upper orextended portion of the trolley pole may turn as far as necessary in aplane at right angles to the plane in which the extended portion of thetrolley pole turns, when the car is rounding a curve or turning acorner, without danger of the trolley wheel 17 leaving the, trolleywire, as sometimes happens in the ordinary construction.

Vhile I have 4shown the preferredembodiment of my invention, it Will beunderstood that minor changes in the details of oonstruction andarrangements of parts may be made Within the scope of the appended claimWithout departing from the spirit of my invention or sacrificing any ofthe advantages of the same.

What I claim is A device of the class described comprising a trolleypole including a stationary portion and a rotatable portion positionedparallel to the stationary portion and beyond the free end of the same,a bearing collar mounted on the stationary portion, said rotatableportion being rotatably mounted in the bearing collar, a bearing blockcarried by one end of the rotatable portion, a trolley head mounted uponthe bearing block and adapted for rotation in a plane at right angles tothe plane in which the rotatable portion of the trolley pole is adaptedto rotate, a trolley Wheel mounted in said head, and means mounted uponthe opposite end of the rotatable portion of the trolley' pole Jforlimiting movement of the same in either direction.

In testimony whereof I hereunto alx my signature in the presence of tvvoWitnesses. A HENRY GRUSONG. Witnesses JOHN H. MCCANN, M. J. MoCANN.
